A lot of colour may be clipped unless you have a very capable display

An application like the excellent colorthink alows you to plot in 3D the various colorspaces (including the accurate ICC profile you made of your own calibrated display [you did do that, right])

I believe that ACES also has a massive potential luminance - you're not going to be able to simulate that without as very capable display 

 

I hope this helps

I was informed I could create a proof setup in Photoshop then whatever colors which are outside of the gamut for the display device, Photoshop could show those colors ?

 

It sounds as if this is not possible and the only way to do this is though the software colorthink ?

The Out Of Gamut Overlay in Photoshop and Lightroom

In this 25 minute video, I'll cover everything you need to know about the Out Of Gamut (OOG) overlay in Photoshop and Lightroom. You'll see why, with a rare exception, you can ignore this very old feature and still deal with out of gamut colors using modern color management tools.

ACES is Elements? 

Whatever, OOG overlay isn't very useful. It predates soft proofing and ICC color management introduced in 1998. The idea at the time was, show an overlay for colors (usually for CMYK) that fall outside the color gamut of (at the time), your display. Use the sponge tool or similar to desaturate until the OOG is gone thus putting the image into gamut. It's slow, crude and also sometimes buggy. You'll deal with OOG colors faster, more precisely using an actual ICC profile and a selection of a rendering intent based on the soft proof you visually prefer. 

The only benefit I can even consider for OOG is to show someone else, who knows very little about color management or image processing why, their printed piece doesn't match the display in terms of saturated colors that simply cannot be reproduced due it falling outside color gamut.

No. Photoshop works on ICC profiles. ACES color management works differently, using monitors calibrated (not profiled) to a standard.

I suppose it might be possible to build an ICC color profile describing whatever space you like, provided you know the primaries, gamma, etc then use Photoshop's proof colours to show out of gamut colours. However I'm not sure how you could handle the extended dynamic range.

You might want to take a look at the link below for a discussion on the integration of Photoshop into an ACES color workflow:

Hi Dave,

I mentioned that article earlier,

I am surprised it didn't contain the help the OP needed, espacially the part Alex Fry added Jan 25,  it seems quite useful to me but iof course I've not tried it.
